Appearing on MSNBC's AM Joy, intelligence expert Malcolm Nance said that President Donald Trump is in no way in the clear, by pointing out huge areas of investigation that special counsel Robert Mueller's report didn't address.

Speaking with host Joy Reid, Nance enumerated multiple questions unanswered about the president.

"The one component that has never been investigated is was he [Trump] compromised?" Nance explained. "They looked at collusion into a criminal conspiracy standard. But whether he was compromised, whether he owes money to Russia, whether he has some personal fealty to Vladimir Putin, that we all see with our own eyes -- that has never been answered."

"Until all of these things are addressed, till we get some clear solid answers, this nation is a national security nightmare," he added.
